Hadoop可视化分析利器之Hue

2016-03-14 12:10 567 查看

http://qindongliang.iteye.com/blog/2212619先来看下hue的架构图：

（1）Hue是什么？

Hue是一个可快速开发和调试Hadoop生态系统各种应用的一个基于浏览器的图形化用户接口。

（2）Hue能干什么？

1，访问HDFS和文件浏览
2，通过web调试和开发hive以及数据结果展示
3，查询solr和结果展示，报表生成
4，通过web调试和开发impala交互式SQL Query
5，spark调试和开发
6，Pig开发和调试
7，oozie任务的开发，监控，和工作流协调调度
8，Hbase数据查询和修改，数据展示
9，Hive的元数据（metastore）查询
10，MapReduce任务进度查看，日志追踪
11，创建和提交MapReduce，Streaming，Java job任务
12，Sqoop2的开发和调试
13，Zookeeper的浏览和编辑
14，数据库（MySQL，PostGres，SQlite，Oracle）的查询和展示

（3）Hue怎么用或者什么时候应该用？

如果你们公司用的是CDH的hadoop，那么很幸运，Hue也是出自CDH公司，自家的东西用起来当然很爽。

如果你们公司用的是Apache Hadoop或者是HDP的hadoop，那么也没事，Hue是开源的，而且支持任何版本的hadoop。

关于什么时候用，这纯属一个锦上添花的功能，你完全可以不用hue，因为各种开源项目都有自己的使用方式和开发接口，hue只不过是统一了各个项目的开发方式在一个接口里而已，这样比较方便而已，不用你一会准备使用hive，就开一个hive的cli终端，一会用pig，你就得开一个pig的grunt，或者你又想查Hbase，又得需要开一个Hbase的shell终端。如果你们使用hadoop生态系统的组件很多的情况下，使用hue还是比较方便的，另外一个好处就是hue提供了一个web的界面来开发和调试任务，不用我们再频繁登陆Linux来操作了。

你可以在任何时候，只要能上网，就可以通过hue来开发和调试数据，不用再装Linux的客户端来远程登陆操作了，这也是B/S架构的好处。

（4）如何下载，安装和编译Hue？

centos系统，执行命令：
yum install -y asciidoc cyrus-sasl-devel cyrus-sasl-gssapi gcc gcc-c++ krb5-devel libtidy libxml2-devel libxslt-devel make mysql mysql-devel openldap-devel python-devel sqlite-devel openssl-devel gmp-devel

1，hue的依赖（centos系统）
Java代码

ant
asciidoc
cyrus-sasl-devel
cyrus-sasl-gssapi
gcc
gcc-c++
krb5-devel
libtidy (for unit tests only)
libxml2-devel
libxslt-devel
make
mvn (from maven package or maven3 tarball)
mysql
mysql-devel
openldap-devel
python-devel
sqlite-devel
openssl-devel (for version 7+)

2，散仙的在安装hue前，centos上已经安装好了，jdk，maven，ant，hadoop，hive，oozie等，环境变量如下：
Java代码

user="search"

# java
export JAVA_HOME="/usr/local/jdk"
export CLASSPATH=.:$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
export PATH=$PATH:$JAVA_HOME/bin

# ant
export ANT_HOME=/usr/local/ant
export CLASSPATH=$CLASSPATH:$ANT_HOME/lib
export PATH=$PATH:$ANT_HOME/bin

# maven
export MAVEN_HOME="/usr/local/maven"
export CLASSPATH=$CLASSPATH:$MAVEN_HOME/lib
export PATH=$PATH:$MAVEN_HOME/bin



##Hadoop2.2的变量设置
export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin
export HADOOP_HOME=/home/search/hadoop
export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export YARN_HOME=$HADOOP_HOME
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop
export YARN_CONF_DIR=$HADOOP_HOME/etc/hadoop
export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin
export CLASSPATH=.:$CLASSPATH:$HADOOP_COMMON_HOME:$HADOOP_COMMON_HOMEi/lib:$HADOOP_MAPRED_HOME:$HADOOP_HDFS_HOME:$HADOOP_HDFS_HOME



# Hive

export HIVE_HOME=/home/search/hive
export HIVE_CONF_DIR=/home/search/hive/conf
export CLASSPATH=$CLASSPATH:$HIVE_HOME/lib
export PATH=$PATH:$HIVE_HOME/bin:$HIVE_HOME/conf


export OOZIE_HOME="/home/search/oozie-4.1.0"
export PATH=$PATH:$OOZIE_HOME/sbin:$OOZIE_HOME/bin

3,本文散仙主要是采用tar包的方式安装hue，除了tar包的方式，hue还能采用cm安装，当然这就与cdh的系统依赖比较大了。

hue最新的版本是3.8.1，散仙这里用的3.7.0的版本
下载地址：https://github.com/cloudera/hue/releases

hue的github地址：https://github.com/cloudera/hue

4，下载完后，解压tar包，并进入hue的根目录执行命令
make apps编译

5，编译成功后，需要配置/home/search/hue/desktop/conf/pseudo-distributed.ini文件，里面包含了hdfs，yarn，mapreduce，hive，oozie，pig，spark，solr等的ip地址和端口号配置，可根据自己的情况设置，如果没有安装某个应用，那就无须配置，只不过这个应用在web上不能使用而已，并不会影响其他框架的使用。

一个例子如下：

6，启动hue，执行命令：build/env/bin/supervisor
Java代码

[search@h1 hue]$ build/env/bin/supervisor
[INFO] Not running as root, skipping privilege drop
starting server with options {'ssl_certificate': None, 'workdir': None, 'server_name': 'localhost', 'host': '0.0.0.0', 'daemonize': False, 'threads': 10, 'pidfile': None, 'ssl_private_key': None, 'server_group': 'search', 'ssl_cipher_list': 'DEFAULT:!aNULL:!eNULL:!LOW:!EXPORT:!SSLv2', 'port': 8000, 'server_user': 'search'}

然后我们就可以访问安装机ip+8000端口来查看了：

工具箱界面：

hive的界面：

在配置hive（散仙这里是0.13的版本）的时候，需要注意以下几个方面：

hive的metastrore的服务和hiveserver2服务都需要启动
执行下面命令
bin/hive --service metastore
bin/hiveserver2
除此之外，还需要关闭的hive的SAL认证，否则，使用hue访问会出现问题。
注意下面三项的配置
Java代码

<property>
  <name>hive.metastore.warehouse.dir</name>
  <value>/user/hive/warehouse</value>
  <description>location of default database for the warehouse</description>
</property>
<property>
  <name>hive.server2.thrift.port</name>
  <value>10000</value>
  <description>Port number of HiveServer2 Thrift interface.
  Can be overridden by setting $HIVE_SERVER2_THRIFT_PORT</description>
</property>

<property>
  <name>hive.server2.thrift.bind.host</name>
  <value>h1</value>
  <description>Bind host on which to run the HiveServer2 Thrift interface.
  Can be overridden by setting $HIVE_SERVER2_THRIFT_BIND_HOST</description>
</property>

<property>
  <name>hive.server2.authentication</name>
  <value>NOSASL</value>
  <description>
    Client authentication types.
       NONE: no authentication check
       LDAP: LDAP/AD based authentication
       KERBEROS: Kerberos/GSSAPI authentication
       CUSTOM: Custom authentication provider
               (Use with property hive.server2.custom.authentication.class)
       PAM: Pluggable authentication module.
  </description>
</property>

除了上面的配置外，还需要把hive.server2.long.polling.timeout的参数值，默认是5000L给改成5000,否则使用beenline连接时候，会出错，这是hive的一个bug。

pig的界面：

solr的界面如下：

最后需要注意一点，hue也需要在hadoop的core-site.xml里面配置相应的代理用户，示例如下：

Java代码

<property>
      <name>hadoop.proxyuser.hue.hosts</name>
     <value>*</value>
</property>


   <property>
     <name>hadoop.proxyuser.hue.groups</name>
     <value>*</value>
    </property>

ok至此，我们的hue已经能完美工作了，我们可以根据自己的需要，定制相应的app插件，非常灵活！
